High fuel flexibility, low emissions

The SGT-700 is derived from the SGT-600 and is designed to offer you higher output and efficiency as well as lower emissions with a wide fuel range capability. This gas turbine is an ideal fit for power generation and mechanical drive applications. With the high exhaust heat, it is also excellent for cogeneration as well as for combined cycle applications.

Thanks to a long lifetime with maximized uptime, low lifecycle cost and easy servicability, the SGT-700 offers you a high lifetime profitability. The robust industrial design offers a low degradation over time.

Ingenious design to the core

The SGT-700 provides the best availability of its class, thanks to a robust and well-proven design. The compact twin-shaft engine is easy to maintain and allows for flexible operation with excellent efficiency at part load conditions.
Using the same design for power generation and mechanical drive increases the operational reliability.

Reliable and easy to maintain

The SGT-700 employs an 11-stage axial-flow transonic compressor incorporating the latest aerodynamics, with variable guide vanes for robust operability and optimized performance over a wide range of operating conditions.

Two-stage free power turbine

The 2-stage uncooled free power turbine offers a nominal shaft speed of up to 6,500 rpm. For mechanical drive, it may operate at 50 to 105 % of the nominal speed. The power turbine can be matched for optimal performance at different ambient conditions.

Packages for power generation and mechanical drive

The SGT-700 package offers you a small footprint and excellent serviceability. It features a modular and flexible design with single-lift capability.
The driver for both the power generation and the mechanical drive package is the same.

SGT-700-based power plants

For combined cycle and cogeneration (combined heat and power – CHP), Siemens offers a broad range of power plant configurations and scopes based on the SGT-700 gas turbine. For combined cycle, 1x1 or 2x1 configurations are part of the standardized portfolio.

Excellent CC and CHP efficiency

High combined cycle performance: In a 2x1 combined cycle configuration, the power output is 91.6 MW(e) at a net plant efficiency of 53.1%.

Low emission capability

The combustor and burner design give world-class emission performance over a wide load range and are capable of low NOₓ emission levels.
Low emission levels are also received on liquid fuel without need of water injection.

Emissions for 100 – 50% load, NOₓ at 15% O₂:

Natural gas: ≤ 15 – 25 ppmv

Diesel No. 2: ≤ 42 – 58 ppmv

Emissions for 100 - 50% load, CO at 15% O₂:

Natural gas: ≤ 10 – 25 ppmv

Diesel No. 2: ≤ 25 ppmv

(Emissions depend upon site conditions, required load range and other project-specific data.)
